Liquid Penetrant Testing

Liquid penetrant inspection (LPI - also referred as DPI or PT) is a non-destructive testing (NDT) process & is a widely applied and low-cost inspection method used to locate surface-breaking defects in both ferrous & nonferrous materials (metals, plastics, or ceramics).

 

All our inspectors have years of experience in Liquid Penetrant Inspection and are qualified to PCN standards.
